Wanted to see if anyone else has had this issue. When im in a project and i double click a plugin in the effects bin sonar freezes and has to be closed. The music can be playin or not and it doesnt freeze everytime and it not the same plugin when it does freeze. it makes me save more often though!

No I haven't seen that.

Nor me.

I would suggest that if this is happening across multiple projects and different plugins, then you might need a re-install

If it's just one project, try rebuilding it, or start from an earlier version, or even one of your backups.

I'm having issues with a few IK plugs.
Namely the CSR reverbs and AmpegSVX.
Both are plugs that have not been updated to 64 bit.
TRackS3.5.1 and Amplitude3.9.1 (both support 64 bit) run fine.
This, BTW, is also true on my 32 bit (OS and Sonar) system.
I'm guessing that something in the coding (including the 32 bit) changed when both plugs added 64 bit support.
I see a C++ dialog flash before the problem reporter (is that right) pops up.
Sometimes I just get the white screen and no "reporter", sometimes the reporter and then the BSOD.
Both plugs (CSR and SVX) work fine in X1d.

HTH,

Tom

its happened on two different projects. and several different plugins. and then it might not do it for a while.
@DeeringAmps, i finally deleted the IK plugs. They were causing other issues.
